'For This Purpose' in the Bible

And all that heard him were amazed, and said, Is not this he that destroyed in Jerusalem those who called on this name? And he hath come hither for this purpose, that he may bring them bound to the chief priests.

But arise and stand upon thy feet; for I have appeared to thee for this purpose, to prepare thee as a minister and a witness both of the things which thou sawest, and of those on account of which I will appear to thee;

He that committeth sin is of the Devil; for the Devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the Devil.
